Abstract
Parietaria L. is a genus comprised of 20 species distributed throughout temperate and subtropical areas of the world. The leaf and pollen characters of four species of Parietaria from different locations in Iran were investigated with light and scanning electron microscopy, in order to assess their diagnostic significance to provide additional evidence on species delimitation. All pollen grains were small in size and found to be porate. Most of the pollen characters, such as shape and sculpturing of pollen grains, exine diameter, were overlapped between species and indicated limited taxonomic value. The pore and annulus diameter could be provided additional taxonomic characters that can be used for species delimitation in the genus. Moreover, the leaf epidermis provided new qualitative data (laminar hydathodes, bladder-based trichomes) that could delimit the species. The characters like twin stomata and laminar hydathode observed in P. officinalis were reported for the first time in this genus.
